SMYRNA, Tenn. (WZTV) — Picture this: You’re enjoying a sunny day and decide to treat yourself to a delicious ice cream sundae. You take a spoonful, savoring the sweetness, but then something feels off. You bite down hard and...wait, what’s that? A sharp crunch that doesn't belong. You might think it’s a nut, maybe a pecan, but then the horrifying truth sets in. It’s glass.
